START ND-STOP DEVICE FOR TALKING-MACHINES.

Application filed. September 9, 1913. Serial No. 788,827.

' Bridgeport, Connecticut, have invented a new' and useful Improvementin Start and Stop Devices for Talking-Machines, which `invention isfully -setforth in the following ,Y speci icatiqn.

This invention relates to automatic stop "i" mechanislmand especially tomechanism for -10 automatically stopping a talking machine,

Vand also, preferably, automatically starting 'l the same, beingdesigned more particularly V for .use in connection withthat class oftalking machines in which a tone-arm or other tu ular sound conductor,together with the disk record in the act of reproducing said records; an.object in vieWf-is to provide av talking machine with` means wherebythe 'machineshall be anton'iatically started when the operator'placesthe .reproducer and tonearm in position to.. commencereproduction,

x ment acrossthe. face of the record, or when and which shall'alsoautomatically stop theV motor when, for any reason, the reproducer andtone-arm shall cease their advancemovetheir speed of advance shall bematerially varied,.as, for instance', decreased below a y en;

predetermined limit. For example, when the reproducer reaches theinterior end of the spiral record groove (by which groove it, isadvanced across the record), the advance movement of the rep'roducerandthe tonearm ceases, and itis one object ofgthe present invention tostop the motor at the same time that the reproducer reaches the end ofthe record.

` Vith this object in view, the preferred em! bodimcnt of the inventionconsists, (in a i402 A rotative element, as the record, and the usualtalking machine) of a motorfor driving a or any suitable tone-armprovided with any desired reproducer, with a stop mechanism such asmeans controlling the application of power to the motor, which means isoperative to permit the supply of -power to the motor' whilel theltone-arnris moved by the y record, but `which automaticallyacts to cut@oli' power from the motor-when the tone-arm vceases to advance, or itsspeed of advance is materially variethras, for instance, decreased belowa predetermlned vllmit. Thus for eX- placed in position to begintherepro'duction of the record2 said switch being maintained 1n closedposition topermit current to pass to thefinotor so long as the tone-armcontinues to advance across the record, 'but being automatically openedto cut off current from the motor when the tone-arm ceases for anyreason to advance across the'face of the record, asV it would cease, forexample, whenl speincation uf Letters Patent. Patented Aug. 14, 191

it reaches the end of the interior convolu tion of the -record groove.It will thus `be seen that the closingand opening of the swltch to startand ,stop the motor is controlled by the tone-arm, thus avoidinsgtheannoying necessitvfheretofore existing for the operator to iist'throwthe switch and l supply power to the motor; then to place the reproducerin position; and, when the reproduction'has ceased, to open the switchto stop the motor. By the'use of the present invention, the operatorneed pay-y no attention whatever to the switching on and oi of thecurrent, since these functions are automatically performed whenthetone-arm is placed 1n position on the record and when it ceases toadvance.

A machine embodying the invention -is provided with a rotating elementadapted to carry the record, and a traveling element in the Vform vof atone arm and reproducer adapted to be 'propelledby the rotating elevmentthrough the engagement of the needle of the reproducer withthe'groovesof the record. .A suitable motor is provided for,

driving the rotating element, and a suitable mechanism is p'rovlded kforcontrolling the movement of the motor and the rotating element, thismechanism serving to automatically stop'the said movement when the ad'vance of the traveling elementacross the rotating "elementv ceases, andlpreferably also serving to start the said movement when the travelingelement is moved Ato a position ad jacent the periphery of the rotatingelement. vThe start-andstop F mechanism preferably comprises adevicewhich acts directly on the m'o'tor, serving to'contiol the inputof power thereto, but it will be understood that -the invention is notlimited to a start-and-stopv device of this form and that wide variationma be made in this part'of the structure wit out departing from thespirit ofthe in-` vention. i

The inventive idea involved- 1s capable of receiving a varietyofmechanical eXpressions, one of which, for the purpose of illustheinvention,"is shown in the acconipanyin drawings, but' it is to vbeexressly un erstood that such drawings are or the "purpose 01Eillustration only and are not ldesigned to de ne the limits of theinvention, reference claims for this purpose.

- In 'said drawings-'- Figure 1 is a top plan view lof the auto-i` maticstart-and-stop mechanism constituting the present invention with theswitch closed; and Fig. .1a a like view with the switch open; s.

Fig. 5 is a broken perspective of a further detail. i

Referring to the drawings, in which like c reference numerals indicatecorresponding parts, 4 is a motor, vrer'erably electric; 5 .is a switchof any suita le or desired construction controlling the iow of currentto said motor, this switch constituting the start-andstop device abovereferred to; 6 is a toneoperatively arm of the usual or any suitableconstrucdesired4 tion; and 7 is a reproducer of any form having-theusual needle for engaging the convolutions of the record groove of thewell-known disk form of record.- The said Atone''arm and reproducerconstitute the aforesaid traveling element, and the said record with itslsupportV constitutes the aforesaid .rotating element 'which propels thetraveling element. Y

A controllingv means 1s provided for the start-and-stop device, in this'case the switch 5, this controlling means'comprising 1n part anactuating mechanism which will now be described. -A shaft 8 driven bythe motor is connected,as'by a worm 9 and worm-gear bearings 12, 12', inthe frame of the motor. Keyed to said worm .shaft 11 is a ratchet wheel13 which is in position .to be engaged byv a pawl 14 pivotallyconnected, at 15, to

harm 17 the projecting end of the switch 5. Said awl vmaybe actuatedeither Vby gravity or y a-spring 16, Fig. 2, to cause it to engage vtheratchetwheel 13.",and when it .soe'ngages n of the shaft 11 saidratchet, the revolut o pull the switch acts through the 'p'awl l theposition being liad to the appended rent turned 'onto the motor.

and thereby open the switch and prevent the f passage of current to themotor, saidopening movement ofthe switch being the tension of a. spring*(not shown) within the switch, this .be a usual or well-lmown form ofswitch. enthe pawl 14 is freed -from the ratchet wheel 13 the switchisclosed '(see Fig. 1) under the action of its spring and current passestothe motor. It will thus be seen that when the paw'l is in enga ementwith the fratchet wheel, the' switc is open, the current cut' o, and themotor brought toastop, and vwhen the pawl is disengaged from the ratchetwheel, the switch -is automatically closed and the-cur- The controllingmeans for the start-andstop device also comprises ntwhanism whereby thepawl 14 will be arglromatically released from the'ratchet in order tostart the.

motor and automatically brought into en.- gagement with the ratchet tostop the motor (all under the control (of the tonearm) and thismechanism will ynow Ibe dei scribed. It comprises two movable memberswhich normallyy engage each other and travel synchronously. One of thesemembers is connected with the motor and the rotating element by meansindependent of' the start-and-stop device, 4,the said means preferablybeing positive in'its action. The other member is driven from thetraveling As shown, thetone-arm is mounted to turn around avertical'axis a horizontal plane and. has projecting radially-there:v`

from, preferably in a plane below the tul; 'table of the machine, alugor arm 18,'F1g2` 1, to which there is pivotally connected a link 19, the.other end-of which is pivotally connected, at 20, to one arm`21 of abellcrank lever pivoted, at 22, to the framework of the machine andhaving its fother arm 23 extending forward and in close proximity to theworm shaft '11, being provided on its extremity adjacent said worm shaft11 with la reduced knife edge 24, Figs. 1 and 3. Also l11o y knife edge24 ofv the lever arm 23 and 'is provided, with a notch 31 for engagementl with-saidknife edge, as clearly illnstrated in full lines in Fig. 3.The extreme Afori ward-end'of the latch 30 is provided von its underside with a cam face 32 for a purpose which will be hereinafterdescribed.

The .said arm 23 'of the ,first lever constitutes a movable membercon?.`

nected with the ytone-arm or traveling element, and the said arm 27 ofthe l*second bell-crank lever constitutes a movable member connectedwiththe Vmotor or the rotatin element. y y

ivoted at 33, Fig. 2, to any'suitable support is a lever 34 whoseright-hand end, as

shown inl Fig. 2,

by the cam 26 on the lever armQ, and the left-hand end of said lever 34:is curved, as shown at 36, and is positioned undera lug 37 projectinglaterally from the side'of the pawl 14, so that when vsaid lever 34 isdepressed at the right of Fig. 2 by engagement y l of the cam 26 Withthe anti-friction lroller 35, the curved end 36 of said lever iselevated, thereby lifting' the pawl 14 out Iof engagement with theratchet 13, and when the cam QG'is out of contact.. with theantifriction 'roller 35, the curved end 36 'of the lever 31is permittedto fall, thus permitting the pawl 14 to come into engagement with 'theratchet 13. Y y

`The pitchA of the'wo'rm 'shaft 11 is such i that itl advances the tooth28 and with it the lever arm 27 along said worm lshaft 11 at the samespeed as lthe tone-arm advances 3()` the knife-edge 2li when saidtone-arm is bei'ng moved across fthe faceof'the recordby theconvolutioi'is of the record groove, and sincethe knife edge 24 and thelatch 30 with the knife edge in the notch 31 advance simultaneously andat the sainey rate of speed, it isvapparent that the knife edgecannotyescape from the notch 31 as long 'as the two continue to advancetogether. W'hen, however, the tone-arm ceases to advance, as would bethe case when the reproducer needle has reached the interior endy of therec- 4ord groove, the revolutions 'of the worm shaft 11 continue toadvance the tooth 28 and with it the latch 30 until the, latch-notch 31is advanced away from the knife edge 424, whereupon the revolutions ofthe worm shaft 11 acting upon the tooth 28 serve to rock.the latch 3i()on its pivot 29, throwing it up free from the knife edge 2aand alsosimultaneously disengaging the tooth 28 from' the worm.' As soon as thetooth is thus disengaged from` the worm, a spring 38,- Fig. 1, acts todraw the lever arm 27 back (tothe position shown Vin Fig. 1a)r againstany suitable stop `39. At the commencement of the operation orengagement of the tooth 28 with the worm 11, the cam 26 has impiiigedupon the roller 35 on the lever 34, and elevated the kend of the leverunder the paivl `11h thus lifting the pawl out 'ofengageinent with theratchet ,'13 and per- 1nit.ting-tlie switch to `be closed under theinfluence of its spring to turn on thewcur'- rent to the motor, and aslong as the tooth;Y

is'provided with `an 4anti-` friction roller 35 ina position to beengaged' yto take place before-the niovenienlts .l

ultimately result inthe aetiiLLtLOllf. Iof vthe shaft 11, the cam `2.6continuesithiistel-act upon the lever 34 and maintain the curved endthereof, and with it tlie pawlyll, in` elevated position. i Butfas soonastthefspring 38 has retractedthearm Q7 andL the` tooth 9.8, when it hasbecome freedfromlthe worm then starts to retract under yfthe influenteof" the switch spring ,and "again falls lintercontact with'the nexttooth on the ratcliet13,

thus maintaining the s witclrin openposition without anyundue orbreakingstrainy 1 upon the parts.

l It will be apparent fromthe-foregoinglil scription that thecontrolling means furthe startend-stop device becomes innnediatehvactive upon thestolnping ofthead'vaiice they tone-aigu. or Itravelingelement, 'it being unnecessary for any preliminary -nioi ,A

stop device.4 i h f N A w It will also be apparent that ythe`controlrhicli ling means for the start-andfstop"device `will becomeimmediately aetive upon a. material variation of the speed `of advance'of the 'tone-arm-vor traveling element, such as a nia terial decrease inits e'speed of advance, for in such event', tooth '12S `may advancelatch30 relatively to knife-edge until latchnotch 31.is moved away from rtheknifeedge, whereupon the relatedparts `will operate as above explained,to yeifect thestopping of the machine. 4 V,

lVhen the parts have thus been brought' to a stop by the opening of theswitch (see Fig.

1?), the lever arm 23 witliits knife edge '2l 'and the lever V2Tn'ith'its tooth will occupy the position `indicated in full lines inFig. 1a, but when the operatortakes hohl of the tone-arm and moves itfrom the cen-` tral portion -of the record outwardlytd its` inoperativeposition' (which latterposition 18 acting through the link 1l) on thelever arnr 21 serves to retract the levernrnr 23 to the dotted lineposition, and tlie'l the p knife edgepa ssesbeyend' the lo\ is shown indottedlines in 13") the lug immediately falls. .When the ytone-arm risgspring df the' switch closes the switch and VV starts'the motor, ,thisoccurring at the inetant when the to0th.,28 comes in contact .1 withVthe commencement ofthe wormen the shaft 11, asshown' in Figs. 1 and 3.There- .2.; upon 'the tone-arm andthe two lever arms 2 3 .27 areadvanced together as before aIt observed that if the tone-arm stopsorf-materially decreases .its speed at an timeor at an p Ace while incontact wit the record, w ether because it reaches the a end of therecord or forany other reason, 'theworm 1 1 willf continue to advancethetooth 28, release the latch 30, and permit the lever arm 27 to bereturned 'by' they spring 38 against the stopV 39 and the cam 26 tobe.30 thrown out of contact vwithdthelever 34, v thereby permitting thecurved end 86 of the lever to all and with it thepawl 14, and the to beopened as just hereinbefore dey It will also be observed that the leverarm 1' 27, through the medium of-'the cam 26, acts to absolutely controlthe-switch 5 and that the position-0f said lever arm 27 determineswhether ory not 'the switch 5 is closed to turn on current tothe motor,or is open to cut oli.

' said current and stop the motor. It will alsobe observed'that as longas the tone,- arm 6 vis being advanced by the record, the .leverarm 23and the lever armv 27 advance as one member and serve to leave'theswitch closed, butl that-the instant the tone-arm e ceases to advance oritsspeed of advance is materially decreased, the two lever arms 23 and27 no longer act as a unit, since the lever arm vv23 stands still, or isrelatively retarded, while the lever arm 27 advances, which differenceAresults in disconnecting vthe two .lever arms'and freeing the lever arm27 from the control of the worm 11, permittlng the l"lever arm 27,.which'action results in the engagement of the pawl 14 with the ratchetand the opening ofthe switch by the power of the motor itself.
